A cultural route that connects Uruguay, Argentina, Brazil, Cabo Verde, Chile, Indonesia, Philippines, Portugal, and Spain? This is an ambitious undertaking only comparable to the Silk Road and Qhapaq Ñan world heritage sites.

"A fascinating trail whose waterways, landscapes and geographical landmarks remains intact as they were seen by Magellan and his sailors 500 years ago." - UNESCO description

The picture above is from the Monument to the Discoveries (1960), located adjacent to the Tower of Belem. Will this route's tangible sites be based on commemorative crosses, monuments, and statues that are located in each country included? Or will this route include already inscribed sites?
